BACKGROUND

Contact lenses are small lenses that are worn directly on the eye andare widely used to correct vision variations. Contact lenses havetraditionally been either rigid (hard) or soft. One importantconsideration in wearing contact lenses is eye health, another isconvenience. Contact lenses are placed directly on the eye.Consequently, it is important that the contact lenses and theirpackaging not introduce any unwanted contamination into the eye.

The more commonly used soft contact lenses are designed to be used for aspecified number of days, and are then to be replaced. For example, manycontact lenses are to be used for only one day after which they are tobe disposed of. This frequent replacement of soft contact lenses ishighly desirable because it is difficult for a patient to sterilize orotherwise adequately clean the inevitable contamination that builds upon the lenses over time.

Another consideration in the use and manufacture of contact lenses isconvenience. Contact lenses that are intended to be replaced more oftenmay not be as convenient to the user because of the frequent need to buyor otherwise replace the contact lenses. In addition, the secondarypackaging of contact lenses is often difficult to understand.Traditionally the contact lenses are provided in a box which may containmultiple ‘blister packages’ of contact lenses. Although for some contactlens wearers only one level or strength of contact lenses is required,many users require a different strength for each eye which maynecessitate the ordering of two different boxes of contact lenses.

Additionally, when contact lenses are purchased online or over thephone, the secondary packaging of the contact lens does not include thepatient's prescription information. This may be problematic, especiallyif the patient requires different strength contacts for each eye becausethe patient may not always remember which contact strength correspondsto each eye. This problem may be compounded if the user does notremember to open a new box of contact lenses before disposing of theprevious set of lenses. It may be difficult for the user to determinewhich of two boxes of contact lenses is intended for a specific eye,especially since the user may have significant visual impairment.

DETAILED DESCRIPTION

The present specification describes systems and methods for providingcontact lenses to users. According to one exemplary embodiment, thesecondary contact lens package provided by the manufacturer includes thepatient's prescription information such as the patient's name, theprescribing doctor's name and phone number, usage information, and otherinformation related specifically to the patient's prescription.Additionally, the present system and method includes a method of doingbusiness in which contact lenses may be stored by a contact lensprovider and supplied the consumer in an efficient and economicalon-demand manner.

Further details of the present exemplary systems and methods will beprovided below with reference to the figures. In the followingdescription, for purposes of explanation, numerous specific details areset forth in order to provide a thorough understanding of the presentsystems and methods. It will be apparent, however, that the presentapparatus, systems and methods may be practiced without these specificdetails. Reference in the specification to “an embodiment,” “an example”or similar language means that a particular feature, structure, orcharacteristic described in connection with the embodiment or example isincluded in at least that one embodiment, but not necessarily in otherembodiments. The various instances of the phrase “in one embodiment” orsimilar phrases in various places in the specification are notnecessarily all referring to the same embodiment.

As used herein and in the appended claims, the terms “primary package,”“primary packaging,” or “primary case” will be used to refer to thepackaging in which a contact lens is placed during the manufacturingprocesses. This package is traditionally a ‘blister’ package but otherprimary packages are also used. Similarly, the term “secondary case,”“secondary contact lens case” and “secondary package” shall be usedinterchangeably and shall be interpreted broadly as including anycontainer or packaging that a lens or supply of lenses may be placed insubsequent to being placed into a primary package. Secondary packagingincludes any box or package that a supply of contact lenses may beplaced in by the manufacturer for delivery to the lens wearer, adistributor, or to another destination.

As used herein and in the appended claims, the terms “manufacturer” or“distributor” will be used to refer to a third party provider ofcontacts lenses who provide contact lenses to individuals based onprescriptions. The terms “manufacturer” or “distributor” may refer toany business, individual, or company that sells or distributes contactlenses, excluding optometrists, ophthalmologists or others who havein-person contact with the patient.

Turning now to the figures, FIGS. 1A and 1B illustrate a frontperspective view and a side perspective view, respectively, of a typicalprior art secondary contact lens package. Similarly, FIGS. 2A and 2Bshow a front perspective view and a back perspective view, respectively,of an alternative prior art secondary contact lens package.

As mentioned previously, the traditional secondary contact lens packages(100) provided by manufactures such as those illustrated in FIGS. 1Athrough 2B fail to notify or otherwise provide the user withprescription information. Consequently, a user may have difficultyidentifying which box or strength of lens is intended for a particulareye. This difficulty is exacerbated by the fact that contact lenses aretypically packaged according to the power or strength of the lenses. Inpractice, a user who does not readily recall their prescription willlikely receive two boxes of lenses with no information indicating whichbox contains lenses for the right eye and which contains lenses for theleft; leaving the patient to decide for themselves.

As shown in FIGS. 1A-1B, traditional secondary contact lens packages(100) provided by manufactures often include a strength or powerindicator (110). They also may include a brand-name (105) and a bar-code(115). Secondary packages may be constructed from any number ofmaterials including, but in no way limited to, cardboard, plastic, orpaper. Furthermore, secondary packages may include, according to variousexemplary embodiments, re-closable mating fasteners (120) such as a taband slot fastening device, Velcro, and/or a resealable adhesive.Typically, secondary packages contain from one to two hundred contactlenses depending on the size of the package and the type of the contactlenses.

According to one exemplary embodiment, the present system includes oneor more primary contact les packages contained within a secondarypackage. According to this exemplary embodiment, the secondary packageincludes prescription information specific to an intended patient. Asused in the present specification, and in the appended claims, the term“prescription information” is meant to be understood as includinginformation specific to a contact lens receiving patient such as aprescribing doctor's information, a phone number of a prescribingdoctor, or personal patient information not traditionally included onsecondary contact lens packages. Various components of the presentsystem will be described in detail below with reference to FIGS. 3through 9.

Referring now to FIG. 3, there is shown a typical prior art primarycontact lens package (300) which is formed in two parts. As illustrated,the primary contact lens package (300) includes a blister pack member(310) which is sealed by a membrane (320) forming a lid on the package(300) and which may be peeled away to release a contact lens (325)contained therein. The primary contact lens package (300) illustrated inFIG. 3 is shown with the membrane (320) peeled away to expose thecontact lens (325). Typically, the blister pack member (310) includes apreformed blister pack having a profiled recess (315) formed thereinwhich provides a recess in which a lens (325) may be placed. Accordingto traditional forming methods, the blister pack member (310) istypically injection molded and the contact lens package (300) iscompleted with the coupling of a sealing membrane (320) which mates witha flange (330) to create a sterile seal. During packaging, the contactlens (325) is immersed in a solution (335) which keeps the lens (325)hydrated until it is removed from the pack (300).

FIG. 4 is a top perspective view of an alternative primary packaging forcontact lenses that may be included in the present exemplary system. Asillustrated in FIG. 4, the exemplary contact lens package (400) includesa center substrate (425) having a top sheet member (430) coupled to thetop surface of the substrate (425). The top sheet member (430) may becoupled to the top surface of the substrate (425) by a secure butdetachable connection such that the top sheet member (430) can beseparated from the substrate (425) with a constant and relatively lowpulling force. Additionally, the top sheet member (430) is coupled tothe top surface of the substrate (425) sufficient to allow the exemplarycontact lens package (400) to be autoclaved. Further, FIG. 4 shows thatthe top sheet member (430) may contain various words and/or imagesincluding, but in no way limited to a brand name (415), a design (420),and/or information about the contact (410), for example, that it is forthe left or right eye, and instructions for use. According to oneexemplary embodiment, contact lenses in their primary packaging may bepre-loaded into one or more contact lens dispensers, as shown in FIG. 5,before being packaged in secondary packaging.

FIG. 5 depicts a contact lens dispenser (500) that may be included inthe secondary packaging as provided by the manufacturer, according toone exemplary embodiment. As illustrated, the contact lens dispenser(500) may include a base member (510) and a hinged lid (515) coupled tothe base member. When loaded into the dispenser (500) of the presentexemplary embodiment, the primary contact lens packaging (520) issuitably flat, allowing each primary contact lens package containing onecontact lens to be independently slid out from the container. As the topprimary contact lens package (520) is removed, the dispenser may,according to one exemplary embodiment, be configured to raise the levelof the remaining packages allowing access to the subsequent package. Thedispenser (500) may also include a retention device (525) configured tosecure the primary contact lens packages (520) to the dispenser.Particularly, according to one exemplary embodiment, the retentiondevice (525) can be configured to hold the primary packages (520) inplace when the exemplary contact lens dispenser (500) is shaken or heldupside-down.

The dispenser may also be configured to separably house the contactlenses and their respective primary contact lens packaging (520)intended for use in the left and right eyes of a patient. In someembodiments the primary packaging (520) may contain a label such as an“L” or “R” in order to allow the user to easily differentiate betweenthe lenses. In other embodiments the primary contact lens packaging(520) may be one color for the lenses intended for use on the left eye,and a different color for the lenses intended for use on the right eye.In yet another exemplary embodiment, the primary contact lens packaging(520) containing a contact lens intended to be worn on a first eye ofthe patient is a first color such as blue, and the primary contact lenspackaging (520) containing a contact lens to be worn on a second eye isa second color such as white.

As mentioned previously, any type of primary contact lens packages,including those illustrated in FIGS. 3, 4, and 5, can be included in thepresent exemplary secondary contact lens package including prescriptioninformation. FIG. 6 illustrates a perspective view of a secondarycontact lens package (600), according to one exemplary embodiment. Asillustrated in FIG. 6, the present exemplary secondary contact lenspackage (600) includes prescription information (640) specific to anintended patient. As discussed above, the prescription information (640)may include information such as the patient's name, the prescribingdoctor, the doctor's phone number, usage instructions, a prescriptionnumber, or other information specifically related to the patient'sprescription. In the present exemplary embodiment, the prescriptioninformation (640) may be printed directly on the secondary packaging.Alternatively, the prescription information (640) may be affixed to thesecondary contact lens package (600) by any number of methods including,but in no way limited to, printing the prescription information onto anadhesive label and attaching the label to the secondary contact lenspackage (600) before the secondary contact lens package (600) is shippedto the patient.

According to the present exemplary system and method, the inclusion ofprescription information (640) on the secondary contact lens package(600) increases the level of safety experienced by a patient when usingcontact lenses. First, the inclusion of personal prescriptioninformation (640) allows a patient to be assured that the secondarycontact lens package (600) containing contact lenses is specifically forthem and contains contact lenses with the proper specifications. Second,the inclusion of a patient's personal prescription information (640)including a prescribing doctor's name and/or contact information willprovide a patient with a convenient reference should questions arise.

Continuing again with FIG. 6, the present exemplary secondary contactlens package (600) also includes according to one exemplary embodiment,a left contact lens power indicator (615) and a right contact lens powerindicator (630). Also included may be a brand name (650), a bar-code(635) and other information regarding the contact lenses, themanufacturer, and the like. According to one exemplary embodiment, theprimary contact lens packages (400) may be disposed within the secondarycontact lens package (600) of the present embodiment. The primarycontact lens packages (400) may be contained individually within thesecondary contact lens package (600) or they may be disposed insidecontact lens dispensers (500) prior to insertion into the secondarypackage. Additionally, the primary contact lens packages (400) may becontained within separate bins or portions of the secondary contact lenspackage (600) indicative of which eye of the patient the contact lensescontained in the primary contact lens packages (400) are intended for.

As illustrated in FIG. 6, the secondary contact lens package (600) ofthe present exemplary embodiment includes a bottom member (610). Thebottom member is preferably made from a substantially resilient and formconserving material such as, by way of example only, cardboard orplastic. The bottom member may be configured to hold any number ofcontact lenses housed in primary contact lens packaging. The bottommember (610) may be enclosed by a plastic covering (645) such as a heatshrink wrap, vacuum sealed plastic, or the like, according to oneexemplary embodiment. This plastic (645) may be substantially clear andconfigured to allow a clear view of the contents of the secondarycontact lens package (600).

FIG. 7 is a perspective view of another exemplary embodiment of asecondary contact lens package. As illustrated in FIG. 7, the secondarycontact lens package (600) includes prescription information (640). Asdiscussed above the prescription information (640), may includeinformation such as the patient's name, the prescribing doctor's name,the prescribing doctor's phone number, usage instructions, aprescription number, or other information related to the prescription.Again, the prescription information (640) may be printed directly on thesecondary contact lens packaging (600). Alternatively, the prescriptioninformation may be printed by the manufacturer or distributor onto anadhesive label and attached to the secondary contact lens package (600)before the package is shipped to the patient.

The exemplary embodiment of a secondary contact lens package (600)illustrated in FIG. 7 also includes a left contact lens power indicator(615) and a right contact lens power indicator (630). Additionally, themarkings disposed on the outer surface of the secondary contact lenspackage (600) may also include, but are in no way limited to, a brandname (650), a bar-code (635), and/or other information regarding thecontact lenses, the manufacturer, etc. Additionally, similar to theexemplary embodiment illustrated in FIG. 6, the primary contact lenspackages (400) disposed within the secondary contact lens package (600)may be located inside contact lens dispensers (500). Alternatively, theprimary contact lens packages (400) may be placed directly within thesecondary contact lens package (600) without any dispensers (500).

The secondary contact lens package (600) of the exemplary embodimentillustrated in FIG. 7 may be made from any number of structuralmaterials including, but in no way limited to, cardboard, plastic,structural paper, or any other substantially resilient material suitablefor the manufacture of containers. According to one exemplaryembodiment, the secondary contact lens package (600) illustrated in FIG.7 is a box structure made from a single sheet of cardboard, formed so asto be able to contain between 1 and several hundred primary contact lenspackages. The secondary contact lens package of the present exemplaryembodiment also includes a mating fastener such as a tab and slotfastener (615) configured such that after the package (600) is initiallyopened, the user is able to re-close the package (600) in order to storethe unused contact lenses.

Exemplary Methods

Referring now to FIG. 8, a flowchart illustrating an exemplary method ofproviding contact lenses to consumers is shown. According to theexemplary method, the secondary contact lens cases provided to consumersinclude personalized prescription information. As illustrated in FIG. 8,the exemplary method (800) includes manufacturing (step 801) contactlenses having different powers and geometries. The contact lenses arethen packaged (step 802) in primary packaging. Once packaged, thecontact lenses can then be grouped (step 803) according to thestatistically most common combinations of power and geometry prescribed.These most common combinations can then be packaged together in asecondary packaging step (step 804). Once packaged, the variouscombinations can then be held in stock until they are printed andshipped (step 805) to the consumer. Further details of the presentexemplary method will be provided below.

As mentioned above, the initial step in the exemplary method includesmanufacturing the contact lenses including different powers andgeometries (step 801). According to one exemplary embodiment, themanufacturing of the contact lenses may be performed according to anyknown lens manufacturing methods including, but in no way limited to,spin-casting, lathe cutting, or cast molding. According to the presentexemplary embodiment, the manufacture of various powers and geometriesmay be performed in batches for each power and geometry, for efficiency.

Once the contact lenses are manufactured (step 801), the contact lensesare packaged in primary packages (step 802). While the manufacturedcontact lenses may be stored in any number of primary contact lenspackages, according to one exemplary embodiment, the contact lenses arepackaged in one of the exemplary primary contact lens packagesillustrated in FIGS. 3 and 4.

Once packaged in a primary contact lens package (step 802) the primarycontact lens packages are grouped according to the statistically mostcommon combinations of power and geometry prescribed by optometrists.Particularly, according to on exemplary embodiment, it is possible toassemble the most frequently prescribed combinations of power andgeometry and thereby have sufficient combinations to satisfy the demandof over 98% of the population. This allows a provider to stock andreadily locate a left and right contact lens supply for a prescribedcontact lens combination. Research suggests that as little as onethousand combinations may be adequate to serve 98 percent of the contactlens wearing population. For example, more than 95,000 people may have aprescription for −3.75 for their right eye and −3.25 for their left. Themanufacture may need to only manufacture and stock a relatively smallpercentage of the total possible combinations in order to fulfill a veryhigh percentage of the orders for contact lenses.

Once the desired lens combinations have been manufactured, packaged inprimary contact lens packages, and grouped according to desiredcombinations, the combinations can be packaged in secondary contact lenscases (step 804). As mentioned previously, the groups of primary contactlens packages can be packaged in any number of secondary contact lenscases, including those illustrated in FIGS. 6 and 7.

The groupings of contact lenses contained in secondary contact lenspackages can be kept as stock by a manufacturer or distributor until arequest for the combination is received (step 805). According to oneexemplary embodiment, once a request for a specified combination isreceived, including a patient's prescription information, the secondarycontact lens package can be marked and shipped. The marking of thesecondary contact lens case can be marked with the patient specificprescription information using any number of marking methods including,but in no way limited to, printing methods to print the informationdirectly on the secondary contact lens box such as laser printing ordot-matrix printing, the application of a label or other adhesivesubstrate containing the prescription information, or other similarmarking means. Alternatively, the prescription information may beimparted onto the secondary contact lens case during manufacture if aspecialized combination of lenses is manufactured for a patient.

The present exemplary system and method allows themanufacture/distributor of contact lenses to increase the convenience ofpurchasing and wearing contact lenses for the patients. According to thepresent exemplary system and method, the patient no longer purchases andreceives two separate packages when ordering a supply of contact lensesfor both eyes. This exemplary method can also decrease costs for themanufacturers. Particularly, shipping both sets of contact lenses in asingle box may significantly decrease shipping costs. Manufacturers havenot heretofore employed the present method because it was thought to betoo difficult to maintain the thousands of different combinationsnecessary to serve the entire population.

It is therefore an exemplary element of the present exemplary method toonly stock a percentage of the possible contact lens combinations,rather than stock the entire range of possible contact lenscombinations. In some exemplary embodiments a manufacturer may onlystock the combinations of contact lenses necessary to serveapproximately 98 percent of the population. Research suggests that aslittle as one thousand combinations may be adequate to serve 98 percentof the contact lens wearing population.

Exemplary Systems

Referring now to FIG. 9, an exemplary system for providing contactlenses to consumers according to the present exemplary systems andmethods is shown. The exemplary system illustrated in FIG. 9 maydecrease the costs for the manufacturers and increase the convenience ofordering and using contact lenses for the end users. As shown, contactlenses are first manufactured and packaged in primary packaging (901,902). The primary packaging may be provided, according to one exemplaryembodiment, with a label indicating which eye the contact lens should beplaced on. The contact lenses (901, 902) can then pre-loaded intodispensing units (903) if desired. According to one exemplaryembodiment, the dispensing units (903) may be configured to securelycontain fifteen left contacts (901) and fifteen right contacts (902) inseparate compartments. This separation of the contact lenses may add tothe overall convenience of the system. The dispensing units (903) maythen be packaged in groups of six for example, in a secondary contactlens package (904).

Although the secondary package (906) depicted contains six dispensers(903), it is understood that any number of dispensers (903) may bepackaged together, including but not limited to one, three, six, ortwelve. The secondary package (906) of the present embodiment alsoincludes a label containing prescription information. This label (906)may serve to reinforce the idea that contact lenses are medical devicesand should be treated accordingly. The label (906) may also provide theuser with usage information and information about the prescribingdoctor. Also located on the secondary package (904) are labels (905)indicating the power of the contact lenses contained within the package(904).

After being labeled, the secondary package may then be shipped orotherwise delivered to the user (907). The effect of providing the userwith a single package containing two powers of contact lenses pre-loadedinto dispensing units may be to make the purchasing and use of contactlenses more convenient.

In conclusion, the present exemplary system, method, and apparatusprovide a more convenient and cost effective way to provide contactlenses to consumers. The inclusion of prescription information on thesecondary packaging, and contact lenses for both eyes pre-loaded intodispensers will simplify the purchasing and use of contact lenses. Thecosts of shipping the contact lenses will also be reduced.
